| Hydromedusae, morphologically resembling the Indo-Pacific leptomedusa Lovenella assimilis (Browne, 1905) (Cnidaria: Hydrozoa: Lovenellidae), are reported for the first time in both the eastern English Channel and the southern bight of the North Sea. Analyses of past zooplankton samples from a long-term monitoring program suggest that this non-indigenous species has been present in the eastern English Channel at least since 2007. Genetic analyses identified specimens as Eucheilota menoni based on nearly identical 18S ribosomal RNA gene, mitochondrial cytochrome oxydase subunit gene I (COI) sequences, and 16S Ribosomal RNA gene. Consequently, published morphological descriptions of L. assimilis and E. menoni were compared, and their species status is... |

| Assessing population connectivity is necessary to construct effective marine protected areas. This connectivity depends, among other parameters, inherently on species dispersal capacities. Isolation by distance (IBD) is one of the main modes of differentiation in marine species, above all in species presenting low dispersal abilities. This study reports the genetic structuring in the tropical hydrozoan Macrorhynchia phoenicea α (sensu Postaire et al., 2016a), a brooding species, from 30 sampling sites in the Western Indian Ocean and the Tropical Southwestern Pacific, using 15 microsatellite loci. At the local scale, genet dispersal relied on asexual propagation at short distance, which was not found at larger scales. Considering one representative per... |

| The present collection was made on the south and west coasts of Madagascar between 90 en 465 meters depth and includes 17 species of calyptoblastic hydroids, belonging to six families: Campanulinidae, Lafoeidae, Campanulariidae, Syntheciidae, Sertulariidae and Plumulariidae. Twelve are recorded for the first time from Madagascar, while three of these are new for the Indian Ocean and one is described as new (Tulpa costata). Endemic species represent half of the collection and are numerically more important than cosmopolitan, tropical-indopacific, and southern species. A comparative study of bathymetrical characteristics of species from Madagascar and around the world allows to distinguish three groups of species: deepsea species, which have a very wide... |

| Three new species of Anthoathecatae (Cnidaria, Hydrozoa) of the rare genus Clathrozoella Stechow, 1921, Clathrozoella abyssalis spec. nov., C. bathyalis spec. nov. and C. medeae spec. nov., are described from New Zealand and Antarctic waters. Along with the previously known C. drygalskii (Vanhöffen, 1910) the genus Clathrozoella now numbers four species. Details of the skeleton, hydranths, nematocysts and gonophores are described and discussed, as is also the position of the newly established family Clathrozoellidae. |

| Forty-six species of the superfamily Plumularioidea (Hydrozoa, Cnidaria) and some material identified to the generic level, collected by the CANCAP and Mauritania-II expeditions of the Rijkmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) in the period 1976-1988, are described, as well as two other species that were used in the present study. In addition to the descriptions, synonymy, variability and geographical distribution are discussed; autoecological data and measurements are also presented. The new species described here are: Aglaophenia svobodai spec. nov., Streptocaulus caboverdensis spec. nov., S. chonae spec. nov., Antennella confusa spec. nov. and Nemertesia anonyma spec. nov. All species are figured. The general... |

| An account is given of some hydroids from the Mid-Atlantic Ridge, collected during dives of submersibles "Nautile" (operated by IFREMER, France) and "Alvin" (operated by Woods Hole Oceanographic Institution, U.S.A). The specimens came from three main sectors of the ridge: 15 species from localities near hydrothermal fields (540-1727 m) SW of the Azores, five species from an area (2565-3902 m) west of the Cape Verde Islands near Researcher Ridge, and one species from a site (4529-4578 m) within the Vema Fracture zone west of Guinea Bissau. In all, 21 species were distinguished, comprising two anthoathecates and 19 leptothecates. The families Lafoeidae and Sertulariidae were best represented, with six and four species respectively. Halecium profundum spec.... |

| Jäderholm's type of Schizotricha antarctica, collected by the Swedish Antarctic Expedition 1901-1903, is redescribed from a syntype in the collections of the Swedish National Museum, Stockholm. The type lot of that species proved to be composite, the material best resembling Jäderholm's (1904, 1905) descriptions and figures has been designated as the syntype. There are two more species in the type lot, that have also been described, but are too poorly represented to be either recognized as one of the described species of Oswaldella or to merit a new specific name; they have been indicated as Oswaldella spec. 1 and spec. 2. Resumen: Se ha revisado y redescrito el material tipo de Schizotricha antarctica Jäderholm, 1904, recogido durante la Swedish Antarctic... |

| Twenty-three species, subspecies or varieties of hydroids of the families Thyroscyphidae and Sertulariidae (Leptolida, Hydrozoa, Cnidaria) are described and figured, originating from north-eastern Atlantic localities visited during the CANCAP and Mauritania-II Expeditions of the Rijksmuseum van Natuurlijke Historie (now Nationaal Natuurhistorisch Museum) in the years 1976-1988 and covering waters around Azores, Canary Islands, Madeira, Cape Verde Islands and the Atlantic off Morocco and Mauritania. Besides notes on the variability of the various species in the large material available, vertical and horizontal distributions are discussed. Observations on the considerable material of Sertularella ellisii (Deshayes & Milne-Edwards, 1836) indicate that... |
